Data collected as part of a hydrogeochemical and stream sediment reconnaissance for Emory Peak NTMS quadrangle in Texas including laboratory data on well water (pp. 1-5) and stream sediments (6-15) as well as field data (pp. 16-171).

Data collected as part of a hydrogeochemical and stream sediment reconnaissance for Presidio NTMS quadrangle in Texas including laboratory data on well water (pp. 1-3) and stream sediments (pp. 4-5) as well as field data (pp. 6-47).

From abstract: Results of a reconnaissance geochemical survey of the Emory Peak Quadrangle, Texas are reported. Field and laboratory data are presented for 193 groundwater samples and 491 stream sediment samples. Statistical and areal distributions of uranium and other possible uranium-related variables are displayed. A generalized geologic map of the survey area is provided, and pertinent geologic factors which may be of significance in evaluating the potential for uranium mineralization are briefly discussed.
